/**
ModifiedBehavior v1.0 by Ron Lancaster based on Ben Nolan's Behaviour, June 2005 implementation.
Modified to use Dean Edward's CSS Query.
Description
----------
Uses css selectors  to apply javascript Behaviors to enable unobtrusive javascript in html documents.
Dependencies
------------
Requires [Dean Edwards CSSQuery](http://dean.edwards.name/my/cssQuery/ "CSSQuery").
Usage
------
Behavior.register(
"b.someclass",
function(element) {
element.onclick = function(){
alert(this.innerHTML);
}
}
);
Behavior.register(
"#someid u",
function(element) {
element.onmouseover = function(){

}
},
getElementByID("parent")
);
Call `Behavior.apply()` to re-apply the rules (if you update the dom, etc).
